Invariance for multiples of the twisted canonical bundle [PDF]

, 2006
In this paper, we show an extension type theorem for twisted pluricanonical sections on a family of smooth projective manifolds (the twisting line bundle being pseudo-effective and having a prescribed multiplier ideal on the central fiber).Comment: A ...

A cosmopolitan parasite of Rattus in the Galápagos rodents raises conservation concerns

Conservation Science and Practice, EarlyView.
We draw attention to a recent study that identified the invasive nematode Mastophorus muris, typically associated with Rattus, infecting two endemic Galápagos rats on islands where no invasive rodents have been previously recorded. This unexpected finding raises concerns about undetected rodent introductions and highlights the urgent need for ...

Bifurcation values of polynomial functions and perverse sheaves [PDF]

, 2019
We characterize bifurcation values of polynomial functions by using the theory of perverse sheaves and their vanishing cycles. In particular, by introducing a method to compute the jumps of the Euler characteristics with compact support of their fibers ...

Introduction: the (im)material spectrum of manuscript and print interaction☆

Renaissance Studies, EarlyView.
Abstract This introductory essay to the special issue on Early Modern English Textual Cultures Between Manuscript and Print first outlines previous research into different kinds of interaction between manuscript and print. Examples of this interplay include, for instance, the transmission of text and images from one medium into another, the use of ...

Open books on contact five-manifolds [PDF]

, 2006
The aim of this paper is to give an alternative proof of a theorem about the existence of contact structures on five-manifolds due to Geiges. This theorem asserts that simply-connected five-manifolds admit a contact structure in every homotopy class of ...

On the mean square of the zeta-function and the divisor problem [PDF]

, 2006
Let $\Delta(x)$ denote the error term in the Dirichlet divisor problem, and $E(T)$ the error term in the asymptotic formula for the mean square of $|\zeta(1/2+it)|$. If $E^*(t) = E(t) - 2\pi\Delta^*(t/2\pi)$ with $\Delta^*(x) = -\Delta(x) + 2\Delta(2x) -

Lower bounds for invariant statistical models with applications to principal component analysis

, 2021
This paper develops nonasymptotic information inequalities for the estimation of the eigenspaces of a covariance operator. These results generalize previous lower bounds for the spiked covariance model, and they show that recent upper bounds for models ...

‘Who is the Gael who Would Not Weep?’: The Book of the O’Conor Don, Fearghal Óg Mac an Bhaird, and Late Bardic Poetry of Exile

Renaissance Studies, EarlyView.
Abstract This article examines how late bardic poetry transforms the condition of exile into a literary mode that reimagines community and tradition. I argue that poetry of lament, blessing and devotion articulates a broader literary consciousness that anticipates modern notions of a national consciousness. The compilation of bardic verse in manuscript
